Problems solved by technology
[0014] The purpose of the present invention is to provide a fixing device and an image forming device in order to solve the above problems, which can hardly cause the temperature drop of the fixing belt to occur, and can easily ensure a sufficient clamping width at the clamping part without increasing power consumption or extending the length of time. The start-up time of the equipment, while suppressing the problem of toner adhering to the pressure member or the fixing belt, improves the separability of the recording medium passing through the nip

The invention provides a fixation facility and image forming apparatus, which is not liable to generate temperature reduction of fixing belt, is easy to ensure enough holding width at holding part point, will not only augment consumption electric power, but also extend actuation time of the facility, restrains the problem that the toning agent is adhered to the pressure-producing part or fixing belt, and simultaneously can improve the separability of recording medium through the holding part. The fixation facility and image forming apparatus include a release agent supply component (51) for supplying the release agent to the surface of a pressurizing parts (31), a cleaning component (52) abutted to the release agent supply component (51) and then cleaning the surface of the release agent supply component (51), and decompressing mechanisms (55, 56) reducing the pressing force of the holding part between the fixing auxiliary roller (22) and a pressurizing component (31) of the foaming flexible layer. The fixation facility and image forming apparatus also include a separating mechanism (58) for separating the cleaning component (52) and the release agent supply component (51) after linkage with the reduction of the press force of the holding part caused by decompressing mechanisms.
Description
technical field [0001] The present invention relates to an image forming apparatus such as a copying machine, a printer, a facsimile machine, or a compound machine thereof, and a belt-type fixing apparatus installed therein. Background technique [0002] Conventionally, in a belt-type fixing device using a fixing belt installed in an image forming device such as a copier or a printer, it is known that in order to form a sufficient nip width at the nip portion while preventing the temperature drop of the fixing belt, The technology is to form a heat-insulating foamed elastic layer (elastomer layer) in the fixing auxiliary roller (fixing roller) that forms a nip portion press-connected to the pressure member (pressure roller) through the fixing belt. (Refer to Patent Document 1 and Patent Document 2). [0003] Specifically, a foamed elastic layer made of foamed silicone rubber (silicone sponge rubber) is formed on the mandrel of the fixing auxiliary roller. The thus-formed f...
